The encoded frame rate options on the VidiU product line are High, Full, Half and Quarter.

The actual encoded frame rate streamed from the device is based on a combination of these two items:

1. the Video Input Resolution of the video source connected to the VidiU (refer to this article for a list of supported video input resolutions)
2. the Frame Rate Setting that has been selected on the VidiU

In most cases, the High frame rate setting is identical to the Full setting. However, the High and Fullsettings have different values if progressive 50 Hz or progressive 60 Hz video input signals are being sent to the device.

Table 2 shows the encoded/streamed frame rate (in frames per second) based on the physical Video Input Resolution (Table 1) and the selected Frame Rate Setting.



Table 1 : Video Input Resolutions:

• i50 (interlaced, 50 Hz) : 576i50, 1080i50
• i60 (interlaced, 60 Hz) : 480i59.94, 480i60, 1080i59.94, 1080i60
• p24 (progressive, 24 Hz) : 1080p23.98, 1080p24
• p25 (progressive, 25 Hz) : 1080p25
• p30 (progressive, 30 Hz) : 1080p29.97, 1080p30
• p50 (progressive, 50 Hz) : 576p50, 720p50
• p60 (progressive, 60 Hz) : 480p59.94, 480p60, 720p59.94, 720p60
